Hi @thomas6886, you are quite welcome! Sorry about the pain to return the tablet.
In fact, so long as the tablet is reasonably modern (<2 years) and has a powered USB port, we should expect no issues to arise in conjunction with the 4C Eye Tracker. I know several users run with Microsoft Surface Tablet quite well.
I am afraid we do not maintain a list of supported tablets at this time as indeed, *most* are quite reliable!
Please let us know if we can be of any further assistance.
